This invention relates to apparatus for.

separating entrained liquid from gaseous materials, as, for example `theseparation of liquors, oil,water, etc., from steam or, other gases, all'of which are encountered in evaporation, lubrication of reciprocating,engines andcondensation in pipelines carrying saturated steam. Theapparatus may bel used, for example, to separate glycerine which isentrained'by the-moisture in the vapor in the to replace thecatch-allshown at 37 in Fig. 1

ofthe patent. Many other uses of the invention will readily suggestthemselves to those skilled in the art.

The object of the invention is to provide an entrainment separator whichwill operate by centrifugal force and in which the separated particleswill be immediately removed from the path of the gaseous material fromwhich a it is separated.

yAnother object of the invention is to proin which the separate liquidmay be collected and in which it will be free fromthe action of themoving gas'from which it is 'separated.

Another object is to provide an entrainment separator which shall be ofimproved lconstruction and operation. Other objects will appearhereinafter.

vide a separator havin a catch-all chamber The invention is exemplifiedin the combi- Fig. 1 is an elevationof one embodiment ofI Fig. 3 is aview similar to Fi 2 showing a somewhat modified form ofthe invention.

In`the 'formi of the invention illustrated p in Figs. 1 and 2, acylindrical shell or casing 10is provided having preferably anoutwardylcurved bottom 11 and a removable cover 12.

ithin the casing 10 is a liner comprising a perforated plate 13 uponwhich there are mounted vertical plates 14 -disposed in cylindrical.formation and spaced inwardly froml thewall 10 to provide an annularspace 15 between the wall and liner. The plates 14 are secured togetherin overlapping relation by rivets 16, the overlapping portions of thevplates being held in spaced relation by Washers 17 to provide tangentialslots or louvers 18.- Some or all of the plates 14 may be provided withoutwardly. bent ianges 19 which extend into the space 15 to form baliesfor intercepting movement of air or gas within the annular space outsideof the liner. The plates 14 when secured together by the rivets 16 formav substantially rigid yhollow cylinder which is secured to the top ofthe perforated lplate 13 by angle brackets 2Q rivetedat spaced intervalsto the top of the 'plate and to the liner. The perforated plate 13 is inturn su ported by angle brackets 21 secured to ba e plates 22 within thespace' 23 below the plate 13. The baille lates 22 may be secured to theside Walls 10 y angle brackets 24. Steam, Orother gaseous matter havingliquid particles entrained therein, is introduced through a conduitl 25passingthrough the side wall 10. and provided .within 'the separatorwith a transmission piece 26 which is flattened to providearectangularopening 27 disposed at one side ,ofthe separator and arrangedto discharge the gaseous ymaterial in a tangential,

direction on the inside of the liner. The opening 27 in the transmissionpiece is preferv ably of a size equalto or .slightly greater than thecros'sfsectionl varea of the conduit 25 so that no rcs'i'stance isoffered to. the entrance vof the steam or gas into the'separator.l Thesteam escapes from the separator through a central pipe 28 supportedfrom the cover 12 and open at its bottom at a position below thetransmission piece 26.*' A helical deflector itl plate 29 surrounds thedischarge pipe 28 and extends from the bottom of the transmission pieceto the bottom-of ,the discharge pipe 23. rllhe deflector platernaybeisupported from the liner by means of angle brackets 30 or othersuitable connection withvthe liner.

The entrance of the steam in a tangential direction from thetransmission piece 26 produces a rapid whirling action within the liner.rll`he helical plate 29- augments' this whirling action, making itnecessary for the steam to circulate about the interior of the separatorbefore it can escape through the bottom of the pipe 28. lhe centrifugalforce set up by the whirling action throws all of the entrained matter,froth, etc., against the inner surface of the plates 14. The liquidparticles impinging on the inner surface of the liner continue to movein the same direction as the vapors and thus immediately pass.

through the louvers 18 between the plates 1d. There is no circulation inthe annular chamher outside the liner. rll`he frictional resistance 'ofthe surfaces would, to a large degree, prevent any circulation in thisspace, but, to further insure quiet in this space, the balies 19 areprovided. When the separated` liquid particles are thrown into theannular space outside the liner, they are therefore removed from furthercontact with the rapidly moving vapors within the liner and are free tosettle at the bottom of the annular space and pass through theperforated plate 13 or around the outer edge thereon into the catch-all23. The complete and immediate removal of the separated particles fromthe path of further. influence of the vapors is a large factor'inproducing the effectiveness and superiority of this device over .devicespreviousl built for this purpose. The perforated\ ottom plate 13separates the vapor chamber from the liquid chamber 23 and prevents therapidly moving vapors from setting up a whirling motion within theliquid chamber and thus picking up liquid from the chamber. 'lhe baleplates 22 assist in preventing rotation of the liquid within the chamber23. The liquidcollected within the catchall is lthus permitted to drainquietl back to the evaporator, receiving tank, welly, or otherreceptacle provided for this purpose. llt will be seen that the searated particles are thrown through the ouvers 18 of the liner into thedead space 15 and the vapors travel in a helical course to the bottom ofthe discharge pipe 281' where they enter the pipe and pass upward4 andout of the separator without crossing the path of the separated liquid.The separator does not depend for its effectiveness on the impact of thevapors against the baiile with the accompanyin forceful and sharp changein direction of ow which causes frictional resistance and reduction inpressure and speed. rlhe vapors enter through the transmission piece andtravel menace through the separator at a high 4velocity following agradual helical path around the dis charge -pipe and along the helicalplates. There is, therefore, no sharp changlng of direction of flow ofthe vapors, substantially no vretardation of velocity and substantiallynoback pressure.

llt will be noted that the separator 1s of adequate size to provide acatchall space below the inner liner. During the operation ofevaporation of many liquids, the llquld may at times prime or boil over.Where the present invention is installed, there 1s ample capacity in thebottom or catchall space 23 to hold any liquor collected in excess ofthe immediate capacity of the return pipe. Thls will retain the liquorout of the path of the vapors and permit it to drain to the evaporatoror other receptacle without danger of being carried over with the movingvapor. h

ln the form of the invention shown in Fig.

3, the entering conduit 31 is smaller than that l shown in Figs. land 2so that a transmission piece is unnecessary for directing the enteringvapors in a tangential direction within the separating chamber. ln thiscase, the upper end of the helical plate 29 is carried past the point ofentrance of the conduit 31 and bent upwardly as shown at 32 to preventany tendency of the entering vapor to circulate 1n the wrong direction.
